Stockholm, Sweden’s capital, built it’s first rail link in 1871. More than a century later, this two-track link was carrying 550 trains per day, and more capacity was needed. In 2009 the city began work on a second 2-track rail link, called Citybanan, which will be completed in 2017 at a cost of about $2 Billion. The project is 3.7 miles long, and includes 2 new underground stations providing direct connections to the existing subway lines. Work is being done below a historic city center and a harbor crossing, through granite, all without disrupting existing transportation services.

Delays and overcrowding on rail services are caused by the fact that Stockholm simply doesn't have enough railway tracks. So we're now constructing more tracks and making room for more trains. The City Line is the new railway for you and for Stockholm -- a six-kilometre commuter train tunnel and new commuter stations at Odenplan and T-Centralen.
